Bengaluru, Karnataka, India Razorthink Full time ₹ 4,00,000 - ₹ 8,00,000 per year

Role Overview

Own the reliability, availability, performance, and security of our databases PostgreSQL, MongoDB, and MySQLrunning container-native, highly available on Kubernetes. Youll design the architecture, automate operations, guide domain teams on optimal schema & query design, and lead backup/restore and disaster recovery (DR) with clear RPO/RTO objectives.

What Youll Do

Architecture & HA

Design and operate HA clusters on Kubernetes (StatefulSets, PDBs, anti-affinity, topology spread, CSI storage, auto-failover).

Choose and operate DB operators/distributions (e.g., Zalando/Crunchy for Postgres, Percona for MongoDB/ MySQL or equivalents); maintain versioning/patching strategy.

Implement multi-AZ replicas, read-replicas, and connection pooling/proxying (e.g., pgBouncer/HAProxy/Envoy) for scale.

Performance & Scalability

Capacity planning, sizing, and benchmarking; own p95/p99 latency and throughput KPIs.

Query/index tuning, VACUUM/ANALYZE/auto-analyze strategies (Postgres), sharding/replica-set tuning (MongoDB), and InnoDB/Group Replication tuning (MySQL).

Data Modeling & Reviews

Partner with domain teams on schema/design reviews, migration strategies (Flyway/Liquibase/Alembic), and query best practices to keep services fast and cost-efficient.

Backup, DR & Compliance

Own backup/restore (base backups, PITR/WAL/GTID, snapshotting), tested DR runbooks, and RPO/RTO targets; run quarterly game days.

Implement data retention, encryption (at rest & in transit), auditing, and access controls (RBAC/KMS/Secrets).

Automation & CI/CD

Everything-as-code: Helm/Terraform/Ansible for DB infra; GitOps pipelines for changes, safe rollout/rollback, and automated smoke checks.

Observability & Ops

Metrics, logs, and tracing with Prometheus/Grafana/ELK/Datadog; alerting on golden signals (availability, saturation, errors, latency, replication lag, disk/IO).

Participate in on-call; drive postmortems and permanent fixes.

Cost & FinOps

Optimize storage classes, compression, caching, and query plans to balance cost vs. performance.

Minimum Qualifications

58 years as a DBA/DBRE with production experience in PostgreSQL plus MongoDB and MySQL (at least two in depth).

Strong Kubernetes fundamentals for stateful workloads (StatefulSets, PV/PVC, CSI, network policies, PDBs).

Deep skills in SQL, indexing, query plans, transaction/locking, replication, and failover.

Proven backup/restore & DR ownership (PITR, cross-AZ/region replicas) with documented RPO/RTO.

Hands-on with automation/IaC (Helm/Terraform/Ansible) and CI/CD for DB changes.

Observability in practice (exporters, dashboards, SLOs, alerting) and rigorous incident management.

Excellent collaboration/communication; confident running schema/design reviews with product teams.

Preferred (Nice to Have)

Experience with pgBouncer, Patroni/Crunchy/Zalando operators (Postgres), Percona Operators (MongoDB/MySQL).
